+A stationary cup with a handle sits on the upper platform. One bowl moves sideways away from the upper position at a constant speed, while another bowl is launched horizontally toward the slope with an initial velocity. Gravity drives a separate gray cup down the slope. At the bottom, the gray cup collides with a coil-spring assembly connecting a low-density plastic component to another object. The impact transfers momentum and compresses the spring mechanism. Motion stops as kinetic energy is converted into elastic potential energy in the coil. This interaction illustrates conservation of momentum and Hooke's law, which govern the system's deformation and rebound dynamics.
